摘要:
A tire rim of a motor vehicle includes a substantially cylindrical body for holding a tire, and a hub connected to the body through radial members, and has an outer face facing, in use, the outside of the vehicle, and an opposite inner face. At least one elongate flexible element associated with the rim can reach a resting configuration within the rim, and a working configuration, extended with respect to the resting configuration, of such a length as to allow the tire to be surrounded, in which each flexible element is wound around the tire to form a snow chain. The rim includes at least one retaining member at a zone of its inner face, to be engaged by a portion of a flexible element in its working configuration.

A magnetic roller 100 for being rotatable on a ferromagnetic surface is provided. The magnetic roller 100 includes a roller wheel 110 having an inner space 112, a magnetic array arrangement 120 and at least one first drive mechanism 130. Further, the magnetic array arrangement 120 is adapted to be swivelably disposed within the inner space 112 of the roller wheel 110. The magnetic array arrangement 120 includes a strong adhesion force side 122 and a weak adhesion force side 124. Furthermore, the first drive mechanism 130 is configured to swivelably drive the magnetic array arrangement 120. The first drive mechanism 130 swivelably drive the magnetic array arrangement 120 to direct the strong adhesion force side 122 towards the oncoming ferromagnetic surface, and, to direct the weak adhesion force side 124 towards the foregoing ferromagnetic surface to enable the roller wheel 110 to move forward on the ferromagnetic surface.

摘要:
The present turbine fan rim, turbine fan airless tire and turbine fan hubcap designs are configured to remove air from under the underside of a moving vehicle when rotated in a particular direction, typically in a forward direction. This air movement can create a vacuum below the vehicle, which can create a down force on the vehicle increasing traction between the vehicle's tires and the road surface and lowering the vehicle's center of gravity. This downward force and partial vacuum can thus increase as the rotational velocity of the tires increases, providing greater traction at higher speeds. An additional benefit to these wheel, airless tire, and hubcap designs is the cooling effect that would be created by the flowing air on brake parts that are located near wheels of nearly all vehicles.

Annular tire overlay (11) for drawing onto the rolling surface of tires (40), which has a tread (17) on its outside and a gripping surface (15) on its inside, which tire overlay (11) is so designed that contact between the rolling surface of the tire (40) and the surfacing of the road is prevented by the tire overlay (11) when the tire overlay has been drawn onto a tire. The said tire overlay (11) is provided with a flange (21) which stops the tire overlay (11) from shifting in the axial direction of the wheel. Advantageously, the tire overlay is additionally stiffened by a flange (21) of planar form to keep the contact area on the surface below small.

The invention relates to an auxiliary device that facilitates the movement of standard pushchairs over sandy or similar surfaces. The inventive device comprises rolling elements consisting of hollow bodies (11 and 11') having a cone frustum-type configuration with few degrees of opening. Said rolling elements can be removably fixed in a coaxial manner to the internal or external area of the wheels of the wheel trains (2 and 2') of the standard pushchair either directly or using a coupling. In this way, the surface of the rolling element which is in contact with the sand is increased considerably. Moreover, the aforementioned hollow part (11) is provided with another part (15) which is used to connect parts 11 and 11'. Furthermore, the invention comprises a front traction handle (6) which can be removed and folded or a removable rear handle (31). Once installed, the elements of the invention are designed so as not to interfere with the normal operation or folding of the pushchair.

A support part of a vehicle, preferably intended for movement on non-protected ground, consisting of a wheel, crawler belt or a shoe of a walking vehicle, comprises supporting elements transmitting the pressure on the ground and capable of driving the ground from under the surface of contact of the support part with the ground, and consisting, in particular, of a plurality of contact surfaces with passages for the ground between them. The contact surfaces are arranged preferably in pairs and symmetrically in relation to the direction of movement of the vehicle, the angle between the surfaces being less than 180 DEG . A vehicle with the described support part exercises a reduced tightening and structure destructing influence on the ground and has a higher cross-country capability.
